After the staff is given to the Queen of Cameron Palace by a Pidgeot, she witnesses the Tree of Beginning start to shine brightly, which also stops the impending conflict of the war.

Hundreds of years later, Ash Ketchum and his friends arrive at Cameron Palace where a festival is being held to celebrate Sir Aaron.

At the festival, Ash, coincidentally wearing a re-creation of Aaron's outfit, competes in a tournament at Cameron Palace and wins, to become the "Aura Guardian" for that year.

[4] Since premiering on July 16, 2005, Lucario and the Mystery of Mew grossed ¥4.3 billion at the Japanese box office, making it the year's second highest-grossing domestic film, behind only Howl's Moving Castle.

The final box office tally is 98.3 percent of the sales of last year, but with the last three movies all consistently passing the 4 billion yen mark, it is considered a market success.

The slight market loss is attributed to stiff competition at the box office from other anime films running at the same time.

He praised the film for its "epic" premise, saying that it had "enough weight to sustain an hour and a half of action", as well as its animation and use of CGI.

He concluded: "Lucario and the Mystery of Mew isn't out to change the face of animation forever, but it's set to entertain, which it does with its fantasy flavor and strong back-story.
